- Page 2 The Multisensor is also optimal to warn of possible mold formation. The MS 100 Multisensor is intended for use in normal living spaces. For outdoor use and in damp rooms, such as sauna or steam bath, a suitable sensor is available from the ESERA website.
- Page 3 EN 61000-6-1, Interference immunity EN 61000-6-3, Interference radiation RoHS Connection diagram The connection diagram is available in the store as a MS 100 separate document. Multisensor The Temperature and Humidity Sensor is connected by screw terminals. The pin assignment of the screw terminals is printed on the printed circuit board.
- Page 4 Control via 1-Wire Controller / ECO 1-Wire Controller The control and data output of the MS 100 Multisensor via the 1-Wire Controller / 1-Wire Gateway is very simplified. The current sensor data is output continuously. No query of the data is necessary and available.
- Page 5 Art. No. 11134 V2 Manual calculation of the sensor values The following formula can be used to evaluate the humidity sensor. VDD = operating voltage (5V), VAD = humidity sensor, analog value of the DS2438, Xsense = light sensor, analog value of the DS2438. Humidity calculation Offset = 0.847847 (Zero Offset V), slope = 29.404604 (Slope: mV/ %RH) Srh = (VAD_new - offset) / (slope / 1000)
- Page 6 In disturbed, commercial and industrial environments, the cable should always be shielded in order to increase the "robustness" or interference sensitivity of the system. Note The above statements on 1-Wire are hints and tips and do not describe any product property or represent any guaranteed product property of the product and the 1-Wire Controllers.
- Page 7 Art. No. 11134 V2 If measurements with an open housing are unavoidable, for safety reasons an isolating transformer must be installed upstream or a suitable power supply can be used. After installing the required tests according to DGUV / regulation 3 (German statutory accident insurance, https://en.wikipedia.org/wiki/German_Statutory_Accident_Insurance must be carried out.
